Yes, but from skimming the code and a couple comments in other email,  
it looks like negotiation of TLS at any time other than connection  
establishment is done using SIGALRM to gnutls, which only starttls.el  
seems to do, and there was a report that it's not working for someone  
on Windows.  I have no idea whether openssl supports something like  
that.  And if a protocol does any special wrapping or encoding of the  
TLS-encoded data, I'm guessing it's not going to work well...
